Hi guys,
I haven't been here a while, but just thought of something that always bothers me, and perhaps some of you deal with this problem as well.
I'm talking about issues with conducted emissions on the AC lines. Now I use a pretty standard input mains filter I put on everything, and then tweak where necessary during testing. But I find this quite stressful at the time, because testing is firstly very expensive, and time is limited as well. But its worse because I dont have a complete grasp of AC filter design, so its almost a trial and error response to any issues seen.
I just place a couple of Y caps, a couple of X caps, and common mode choke on every product.
How do you guys deal with this kind of problem? Do you have any set designs you use? Ways of simulating the filter response, additions etc?
